Motor Vehicles and Long Range Transport of Pollutants-A Growing Global Problem 851209
Motor vehicles account directly for up to one-sixth of the total H-ion deposition in the Eastern United States and substantially more in the West. Vehicular pollutants may also play an important catalytic and synergistic role in acidic deposition. In addition, however, motor vehicles clearly cause or contribute in a major way to ozone, hydrocarbons, lead, total nitrogen and other transported air pollutants. It is increasingly clear that whether the goal is to reduce acid rain specifically or transported air pollutants generally, increased control of motor vehicle emissions is important and perhaps essential.
